今天我做实验的时候碰到的，程序连接报错的信息如下：

The authentication endpoint Username was not found on the configured Secure Token Service! 

我用浏览器同样的账号可以登录啊，怎么回事。

上服务器查看，可以看到AD FS的日志中包括如下错误(Event ID为102，Source为AD FS)：

There was an error in enabling endpoints of Federation Service. Fix configuration errors using PowerShell cmdlets and restart the Federation Service.

Exception details:
System.ServiceModel.AddressAlreadyInUseException: There is already a listener on IP endpoint 0.0.0.0:808. This could happen if there is another application already listening on this endpoint or if you have multiple service endpoints in your service host with the same IP endpoint but with incompatible binding configurations. ---> System.Net.Sockets.SocketException: Only one usage of each socket address (protocol/network address/port) is normally permitted

看到这个错误就知道了。因为我的环境是所有的都安装在同一台服务器上导致的，解决方法也很简单，打开PowerShell执行下如下命令：

Set-ADFSProperties –nettcpport 809

然后再重启下AD FS服务即可。

博客园另外一篇博文：Dynamics CRM2013 Server2012R2下IFD部署遇到There is already a listener on IP endpoint的解决方法 也提到这个。
